The only thing I can really think of is applique....Unless you have southwest fabrics then I would suggest a motion pattern type quilt because the southwest can be busy. Pinwheels, or stars within stars. Southwest can be done in so many different motifs...the old west or the southwest aquas and peaches...love pics of the fabric. I grew up in NM so my idea might be different....Hope that helps and great luck I've seen some beautiful quilts in NM
